Announcing NetBSD 2.1
Introduction
The NetBSD Project is pleased to announce that release 2.1 of the
NetBSD operating system is now available.
About NetBSD 2.1
NetBSD 2.1 is the first maintenance release of the netbsd-2 release
branch. This release provides numerous functional enhancements,
including support for many new devices, hundreds of bug fixes, patches
and updates to kernel subsystems, and many enhancements to the user
environment. In addition, all of the security fixes and critical bug
fixes from the NetBSD 2.0.3 update are included as well.
Complete source and binaries for NetBSD 2.1 are available for download
at many sites around the world. A list of download sites providing
FTP, AnonCVS, SUP, and other services is provided at the end of this
announcement; the latest list of available download sites may also be
found at:
http://www.NetBSD.org/mirrors/
We encourage users who wish to install via a CD-ROM ISO image to
download via BitTorrent by using the torrent files supplied in the ISO
image area. BitTorrent has recently been added to the list of
distribution mechanisms and its use is strongly encouraged to help
keep bandwidth available.
About NetBSD
The NetBSD operating system is a full-featured, open source, UNIX-like
operating system descended from the Berkeley Networking Release 2
(Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2. NetBSD runs on 54 different
system architectures featuring 17 machine architectures across 17
distinct CPU families, and is being ported to more. The NetBSD 2.1
release contains complete binary releases for 48 different machine
types.
NetBSD is a highly integrated system. In addition to its highly
portable, high performance kernel, NetBSD features a complete set of
user utilities, compilers for several languages, the X Window System,
firewall software and numerous other tools, all accompanied by full
source code. The NetBSD Packages Collection contains over 5500
packages and binary package releases for a number of platforms are
currently in progress.
More information on the goals of the NetBSD Project can be procured
from the NetBSD web site at:
http://www.NetBSD.org/Goals/
NetBSD is free. All of the code is under non-restrictive licenses, and
may be used without paying royalties to anyone. Free support services
are available via our mailing lists and web site. Commercial support
is available from a variety of sources; some are listed at:
http://www.NetBSD.org/gallery/consultants.html
More extensive information on NetBSD is available from the NetBSD web
site:

NetBSD is the work of a diverse group of people spread around the
world. The "Net" in our name is a tribute to the Internet, which
enables us to communicate and share code, and without which the
project would not exist.
Major Changes Between 2.0 and 2.1
The complete list of changes can be found in the CHANGES-2.1 file in

About the NetBSD Foundation
The NetBSD Foundation was chartered in 1995, with the task of
overseeing core NetBSD project services, promoting the project within
industry and the open source community, and holding intellectual
property rights on much of the NetBSD code base. Day-to-day operations
of the project are handled by volunteers.
As a non-profit organisation with no commercial backing, The NetBSD
Foundation depends on donations from its users, and we would like to
